 Newton's Three Laws of Motion," and are as follows: (1) All bodies continue in a state of rest, or of uniform motion in a straight line, unless acted upon by some external force that compels a change.

...which he believed were applicable to the planets. Newton's laws of motion are : 1. Every body continues in a state of rest or of uniform motion in a straight line unless acted upon by an external force. 2. When a body is acted upon by an external force, its acceleration... | |
